It's a bad simile! Because it just doesn't happen!
We pick our mates, and they us, on compatibility. If we don't, the marriages won't last, no matter what!
So, if a CD picks a mate that he knows dresses sloppy, with little regard for how fem she looks, then her walking around in work boots, loose jeans and T shirt, wouldn't be a surprise!
On the other hand, if she makes a point to always look her fem best when they meet, she MAY slack off after marriage but is VERY UNLIKELY to become a total macho looking woman!
In that same vein, an SO that picks a CDing partner, whether they know he does or not, LIKES his male/fem characteristics! When he starts openly dressing it CAN'T be as big a shock as Vanessa writes above, can it?
It's NOT like they pick a big macho lumberjack type and one day come home to find him putting on makeup! I DON'T think THAT happens often enuff to mention!
